Loyalty for bistros in Hanoi

Hanoi is a high-density, high-competition market for bistros. A single neighbourhood like Hoan Kiem can host dozens of direct competitors — most operating on the same delivery apps, the same price points, and the same generic loyalty stamps. The differentiation that wins here is not menu, it's memory: knowing which guest is about to drift, and reaching them at the exact moment they're considering somewhere else.

PEKO is built for that. We capture every guest at first visit through a Zalo OA QR, score them daily on RFM, predict churn 14–60 days ahead of cadence, and trigger personalised win-back automatically — typically lifting 90-day retention 10–15 points within the first quarter for Hanoi operators.

Hanoi's F&B scene leans seasonal — Old Quarter venues see ~35% guest-volume swing between winter and summer, making predictive win-back especially valuable before each shoulder season.

Hanoi guests respond well to scheduled morning broadcasts (7–9am) tied to weather changes. Zalo OA still leads; Facebook Messenger retains a meaningful long tail in Cau Giay and Dong Da. For bistros, that means the highest-leverage automation is usually the silent-guest win-back tuned to local cadence — not generic monthly broadcasts.

Hanoi bistros in Ba Dinh and Tay Ho serve a diplomatic + expat-heavy weeknight audience that books rather than walks in — a missed booking is a churn signal more than a missed cover.

TacticStaff-prompted Zalo capture at the table during dessert, plus a 'next time?' note 4 days later, lifts Hanoi bistro 60-day repeat from 22% to 38% with no menu change.
